Genetic antennas are also known as evolved antennas and they often resemble paper clips bent in different ways and connected to a radiofrequency connector. Unlike usual antennas which
Looking at the spectrum of digital signals which are usually seen on amateur radio bands. Demonstrating how to adjust the span so that the width of the signal
Electrets are the electrostatic equivalents of permanent magnets. While a permanent magnet has two magnetically charged poles, an electret has two electrically charged ends. It has internal and
Listened to the downlink frequency of the cross band repeater on International Space Station just now. It was an 80 degree maximum elevation visible pass in my region.
Supercapacitors are also known as ultracapacitors. They are high value capacitors much above the usual electrolytic capacitors which we use in our hobby electronics projects. As an example,
Sometime back we had discussed about diplexers used for LEO satellite operations and duplexers used for repeaters. Diplexer is meant for two different bands like VHF and UHF
Raduino circuit board supplied with µBITX has an arduino soldered to the Raduino board, control lines for the display unit, Si5251 a PLL clock generator chip, 5V regulator
It is common knowledge among radio amateurs that a 40m center-fed half wave dipole antenna will work very well on 15m. That is because center fed dipole antennas,
